5 of 5 annual reports on record have their filing text cached on this host; the rest are listed with their EDGAR link and no extraction, because this surface never fetches from SEC on a page load.

  • Item 3 and Item 9A are located in the filing HTML already cached on this host and read with the same line-anchored item matcher and largest-gap body disambiguation the filing-narrative pass uses for Item 1A and Item 7 — no fetch, no model, no summarization.
  • A heading is accepted as a section only when it is not a table-of-contents row (a trailing page number), not a quoted reference in prose, and names its own section; the span must then clear a per-item length band and carry readable text after the heading. Anything that fails a gate is served as 'not extracted' with the reason — never as a default value.
  • An effectiveness conclusion is read only from a sentence that names its own control set (disclosure controls and procedures, or internal control over financial reporting) and states an outcome. Conditional sentences — the standard limitations paragraph and forward-looking remediation language — are excluded, because they are hypotheses rather than conclusions.
  • When a filing's own sentences disagree — an effective conclusion beside an unremediated material-weakness disclosure, or two conclusions of opposite sign — no verdict is asserted. A wrong 'controls were effective' reading is worse than no reading.
  • Every verdict is shown beside the verbatim sentence it was read from. The excerpt is the filing's own words, capped at 1,200 characters; the filing itself is one link away.
